Want to advance the timing on my EA for premium fuel (BP Ultimate98)
Im told to do this i need to put my car into diagnostic mode first.

I was told by another forum user that to do this there is a white connector on the right hand strut tower. All i need to do is bridge the first 2 contacts (top and bottom)

I looked under my bonnet and was unable to find the whice connector. There are a few other plugs there however.

1) A largeish black plug, with 2 wires going into it. 1 is black with a white stripe, the other white with a black stripe.

2) A Small grey plug, with only a white wire with red stripe.

3) A red wire with a bullet type connector socket on the end

4) A Small grey plug, with only an orange wire.

5) A small white plug with a green wire, and an orange wire.

Does anybody know what these are?

OR can anybody tell me how to get my car into diagnostic mode, keeping in mind the plugs that are in the location that was described to me.

So there's nothing near the interior fuse box on an EA?

Ok so this connector im looking for is on the inside of the car ?
it was explained as being near the front right strut tower, so i assumed under the bonnet. I will go have a look.. Thanks

Nah i wouldnt take my word for it - i dunno much about EAs. But worth a look as this is where ford put the connector on my car

Hey there 4.9...

No such luck, theres lots of white connectors behind the fuse box, however all are plugged into something, not exactly sure what im looking for to be honest... Anyone else able to give detailed info on gettin my EA into diagnostic mode? Somebody must know !

OK here it is,

You need to earth the 'self diagnosis input connector" this is located near the brake master cylinder, it is a single wire with a small plug on it. According to the wiring diagram it is a white wire.
There is a larger plug next to it, this is the output connector, you do not touch this one to check base timing only the input connector. I remember I use to earth it to a strut bolt using a small jumper lead I made up.

Thanks for the help guys. Found some info elsewhere, and that last post confirms it... Adjusting the timing tomorrow.. Will let you all know how i go !

Thanks again !
